Sweet Potatoes in Air Fryer
I’ve been making hundreds of recipes with sweet potatoes for over a decade – from curries to soups to tacos and more – and honestly air fryer sweet potatoes might just be my favorite. They are one of the easiest side dishes to make – and this recipe is the quickest out there! These sweet potato cubes take only 10 minutes to cook, are extremely versatile (I love them on salads or a even a breakfast side), require no pre-soaking, and are a less-mess recipe with easy cleanup. After lots of taste testing, I discovered a little sprinkle of cornstarch gives these sweet potatoes the a crispier exterior while still having that tender, sweet inside and makes these air fryer sweet potatoes a family favorite!

How to Air Fry Sweet Potato
Preheat & Prep
Preheat air fryer at 400 F for 5 minutes while you prep your sweet potato.
Wash your sweet potato and peel it. Using a sharp knife, cut off the ends of the sweet potato.
Then cut it lengthwise and then horizontally.
Cube & Coat in Spices
Cut into 1 inch cubes. If possible, try to cut them as uniformly as possible for even cooking.
In a large bowl, toss your cubes with the oil, cornstarch, and spices.
Air Fry
Spread your cubes evenly in the air fryer basket. If you have a small air fryer, consider doing two batches to obtain optimal crispiness.
Air fry for 8-10 minutes, giving it a gentle shake halfway through, until your cubes are tender to your liking (use a fork to pierce a sweet potato to check tenderness).
.*Every air fryer is a little different, so your cooking time may vary slightly.

Sweet Potato Air Fryer FAQs
Overcrowding in your air fryer basket: When the air fryer is overcrowded, the cubes don’t get evenly cooked and end up less crisp (and sometimes soggy!) If you have a smaller air fryer, you may have to cook in two batches. Cook in a single layer, if possible.
Not shaking the basket: this helps the cubes cook evenly. I like to shake at least once, halfway.
No cornstarch/arrowroot powder: just a small amount adds some crispiness to the sweet potatoes!
Although I have not tried it personally, I don’t see why not! There are so many variations of sweet potato – from the classic orange sweet potato, to white (Hanna) to purple (Stokes, Okinawan), to Murasaki (Japanese Sweet Potatoes). I’m a huge fan of the Japanese sweet potato and will definitely be trying this recipe with those!
Nope! This is a myth. Unlike regular potatoes, sweet potatoes have less starch, so they don’t require soaking to get crispy.
This is totally optional. The skin adds lot of nutritional value. For this recipe, I personally prefer a peeled sweet potato for a smooth exterior that looks more uniform with the other cubes – but you do you!
